Orange Sky: Homeless laundry service prepares to launch in Darwin

A charity which gives homeless people the chance to wash their clothes and shower is set to launch in Darwin by the end of June.

Orange Sky Laundry have been fitting out the mobile laundry at its headquarters in Brisbane over the past few weeks.

Darwin's van will have two washing machines and two dryers, plus a shower in the back of the vehicle.

Co-founder Nicholas Marchesi told 9NEWS, "a really simple thing like having some fresh, clean clothes, having a shower, can make a massive difference in someone's life."

"Over the next couple of days the van will really come together by adding that shower in the rear, adding the water tanks, adding the washers and I guess all the ability to make this mobile laundry come together in this small van."

Once fitted out, the van will be tested on Brisbane streets before making the long journey north to Darwin.

The charity has always wanted to bring its free service to the Northern Territory, where the rate of homelessness is 12 times the national average and the highest in the country.
